Artists are mystics rather than rationalists. They leap to conclusions that logic cannot reach.
Sol LeWitt[The artist's aim is] not to instruct the viewer, but to give him information... . The artist would follow his predetermined premise to its conclusion, avoiding subjectivity. Chance, taste, or unconsciously remembered forms would play no part in the outcome. The serial artist does not attempt to produce a beautiful or mysterious object but functions merely as a clerk cataloguing the results of his premise.
Sol LeWittWhen an artist uses a conceptual form of art, it means that all of the planning and decisions are made beforehand and the execution is a perfunctory affair. The idea becomes a machine that makes the art.
